He said: "This is a metal festival by the fans, for the fans, and the reason we took a chance on giving Mastodon their first UK headline slot and having Twisted Sister up there was because that's what the fans told us they wanted.

"We don't hide away in an office. I've been walking around the site so much that my feet are killing me! I want every fan to have the kind of experience I would want to have a festival and I want them to have a good experience at every touch point at Bloodstock."
